    Abstract: A door closer and assist system that utilizes a door closer and door assist that aids in reducing the force required to open the door and/or increasing the force for closing the door. The door closer may be installed along with the door assist, or the door assist may be installed to any door closer that is already installed to a door. The door assist may include a track and a drive assembly having a motor assembly, a carriage, and a drive shaft. The motor assembly may have a drive train, a motor, and a controller. One or more sensors may be used to determine when to activate the motor to aid in opening and/or closing the door. The door closer and assist system allows for a door to be closed with a force that is greater than or equal to the force required to open the door.

    Abstract: A fastening system including a structure holding element fastenable to a structural component. The fastening system includes a component holding element fastenable to a component to be fastened and movable relative to the structure holding element between first and second operating positions. A first lever element is connected to the structure holding element to be rotatable about a first rotation axis and is connected to the component holding element to be rotatable about a second rotation axis. The fastening system includes a connection element, connected to the component holding element to be rotatable about a third rotation axis and connected to the structure holding element to be displaceable in translation relative to the structure holding element, such that the second rotation axis, when the component holding element is transferred from its first into its second operating position, is displaced in a plane extending perpendicularly to the second rotation axis.

    Abstract: A door open and close mechanism for opening and closing a plurality of doors in a machine tool including a cover. The door open and close mechanism includes a linkage mechanism and a slide mechanism. The linkage mechanism is disposed between an operation door and an intermediate door. The linkage mechanism associates the intermediate door with the opening and closing of the operation door. The slide mechanism is disposed between the operation door and the linkage mechanism. The slide mechanism enables the operation door alone to open and close by a predetermined moving distance. When the operation door is operated to open and close within the moving distance, the operation door alone opens and closes by the slide mechanism. When the operation door is operated to open and close beyond the moving distance, the intermediate door opens and closes in association through the linkage mechanism.
